Honored Contributor --- Quote Start --- A different point is, that the filter specification doesn't make much sense for a high-order FIR filter. The problem is, that "order 55" doesn't represent more than a single cycle at the 10 Hz cut-off. This implies, that the filter coefficients don't give much freedom of tuning the filter shape around the cut-off frequency, which would usually be the purpose of a FIR filter. I expect, that a low order IIR filter gives similar performance in this case. You should try yourself with a filter software tool. --- Quote End --- I think I understand your point, but not completely, I´m starting whith FIR and IIR filters so I'm going to check over my desing
